Abstract
A load interrupter device is provided for live front padmounted high voltage switchgear unit wherein circuit interruption is independent of the speed at which a lineman opens the switch of the switchgear. The interrupter includes an insulating body having a fixed terminal and a moveable terminal spaced therefrom which forms a part of manually operable switch structure. A conductive element within the body connected to the moveable terminal normally engages the fixed terminal. A pair of moveable conductive members are also provided in the body, with one of the conductive members normally engaging a contact electrically connected to the first terminal, while the second member is joined to the second terminal for movement therewith. Spring mechanism interconnecting the two members and in association with a detent causes the first conductive member to be retained in engagement with its associated contact until after the conductive element clears the first terminal whereupon the first conducting member is then acceleratedly moved out of engagement with the first contact to break the circuit and create an arc which is rapidly suppressed by material making up a part of the interrupter body.
